They all used bolts, not lug nuts so your's have been changed Terry. Probably a good thing as more types of wheels will fit and they're probably a lot easier to deal with. But originally, all used lug bolts. The ones on Edgar's J have been modified to use studs so the mag wheels could be installed. Whoever did it did a great job - that person even left the alignment pins on the hubs which fit nicely between the sculpturing on the back side of the spokes. The studs are a lot easier to work with than aligning that pin in the hole and wrestling to get the wheel lined up as you try to start the bolts.
